Checking Default Cluster Plugins

Some of the CSS enhancements over open-source OpenSearch are delivered as default cluster plugins. These plugins are automatically injected to each cluster node during cluster creation and are loaded when the JVM process starts. CSS allows you to check these plugins through the web console or via a standard RESTful API.

Constraints

The default cluster plugins cannot be manually uninstalled.

Checking the Plugins on the CSS Console

Quickly check all default plugins supported by the current cluster without writing any code.

  1. Log in to the CSS management console.
  2. In the navigation pane on the left, choose Clusters > OpenSearch.
  3. In the cluster list, click the name of the target cluster. The cluster information page is displayed.
  4. Choose Cluster Settings > Plugins.
  5. On the Default Plugins tab, check the default plugins supported by the current cluster.

Checking the Plugins via an API

Check the loading of default plugins on specific cluster nodes through an API, for example, when you need to troubleshoot the tokenizer.

  1. Log in to the CSS management console.
  2. In the navigation pane on the left, choose Clusters > OpenSearch.
  3. In the cluster list, find the target cluster, and click Dashboards in the Operation column to log in to OpenSearch Dashboards.
  4. In the left navigation pane, choose Dev Tools.
  5. Run the following command to check the cluster's plugins: 
    GET _cat/plugins?v

    Example response:
